与spring的结合
首先下载springFactory.java,内容如下:
import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.NoSuchBeanDefinitionException;
import flex.messaging.FactoryInstance;
import flex.messaging.FlexFactory;
import flex.messaging.config.ConfigMap;
import flex.messaging.services.ServiceException;
public class SpringFactory implements FlexFactory
{
private static final String SOURCE = "source";
public void initialize(String id, ConfigMap configMap) {}
public FactoryInstance createFactoryInstance(String id, ConfigMap properties)
{
SpringFactoryInstance instance = new SpringFactoryInstance(this, id, properties);
instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));
return instance;
} // end method createFactoryInstance()
public Object lookup(FactoryInstance inst)
{
SpringFactoryInstance factoryInstance = (SpringFactoryInstance) inst;
return factoryInstance.lookup();
}
static class SpringFactoryInstance extends FactoryInstance
{
SpringFactoryInstance(SpringFactory factory, String id, ConfigMap properties)
{
super(factory, id, properties);
}
public String toString()
{
return "SpringFactory instance for id=" + getId() + " source=" + getSource() + " scope=" + getScope();
}
public Object lookup()
{
ApplicationContext appContext = WebApplicationContextUtils.getWebApplicationContext(flex.messaging.FlexContext.getServletConfig().getServletContext());
String beanName = getSource();
try
{
return appContext.getBean(beanName);
}
catch (NoSuchBeanDefinitionException nexc)
{
ServiceException e = new ServiceException();
String msg = "Spring service named '" + beanName + "' does not exist.";
e.setMessage(msg);
e.setRootCause(nexc);
e.setDetails(msg);
e.setCode("Server.Processing");
throw e;
}
catch (BeansException bexc)
{
ServiceException e = new ServiceException();
String msg = "Unable to create Spring service named '" + beanName + "' ";
e.setMessage(msg);
e.setRootCause(bexc);
e.setDetails(msg);
e.setCode("Server.Processing");
throw e;
}
}
}
}
接着在services-config.xml里加入:
<factories>
<factory id="spring" class="包名.SpringFactory"/>
</factories>
我们在applicationContext.xml里配置bean
<bean id="testFactory" class="HelloWorld"/>
在remoting-config.xml里加入:
<destination id="testFac">
<properties>
<factory>spring</factory>
<source>testFactory</source>
</properties>
</destination>
后台已经配置完毕,在前台:
<mx:RemoteObject id = "ro" endpoint="/TestFlex/messagebroker/amf" destination="testFac" result = "resultHandler(event)"/>
可以看出remoting-config.xml里配置起到了中转的作用
